1. What is Mechanical Energy?

Mechanical energy is the sum of kinetic energy and potential energy in a system. It represents the total energy of an object due to its motion and position.

2. How Does the Calculator Work?

The calculator uses the mechanical energy equation:

Where:

• \( ME \) — Mechanical energy (Joules)
• \( KE \) — Kinetic energy (Joules)
• \( PE \) — Potential energy (Joules)

Explanation: This equation follows the principle of conservation of mechanical energy in systems where non-conservative forces are negligible.

3. Importance of Mechanical Energy Calculation

Details: Calculating mechanical energy is essential in physics and engineering for analyzing systems, predicting motion, and understanding energy transformations in mechanical systems.

4. Using the Calculator

Tips: Enter both kinetic and potential energy values in Joules. All values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of mechanical energy?
A: Mechanical energy is measured in Joules (J), the same unit used for both kinetic and potential energy.

Q2: Is mechanical energy always conserved?
A: Mechanical energy is conserved only in systems where non-conservative forces (like friction) are absent or negligible.

Q3: Can mechanical energy be negative?
A: No, mechanical energy cannot be negative as both kinetic and potential energy components are always non-negative values.

Q4: What's the difference between kinetic and potential energy?
A: Kinetic energy is energy of motion, while potential energy is stored energy based on position or configuration.

Q5: How is this different from total energy?
A: Mechanical energy is a subset of total energy, which may also include thermal, chemical, nuclear, and other forms of energy.
